4 Claims.

This invention relates to new and useful improvements in sinewextracting devices, and relates more particularly'to a device of thischaracter having improved means for supporting the leg of a turkey,chicken or other fowl while the sinews or tendons are being extracted orwithdrawn from the edible portion of the leg.

Devices of this general type have been in use, but to a large extentthey have been unsatisfactory for the reason that they have been. ofsuch dimensions, in order to secure proper leverage, as to consume alarge area in which to be operated. It is accordingly one of theprincipal objects of the present invention to provide a device forwithdrawing the tendons from the leg of a turkey or other fowl whichwill occupy a minimum of space, both when in operation and when thedevice is not in use.

A further object of the invention is the provision of improved means forfirmly securing the lower or bony portion of the leg while the sinewsare being extracted. Yet another object of the invention is theprovision of an improved device of this character having means forfirmly supporting thelegs of fowl of different sizes. Still anotherobject is to provide an improved type of supporting means for sinewextractors.

In the drawing:

Fig. 1 is a broken perspective view of the preferred embodiment of thepresent invention.

Fig. 2 is a side elevation thereof, the view showing a special adaptorin operative position, such adaptor being used to receive and firmlysupport a relatively small leg while the sinews are being extractedtherefrom.

Fig. 3 is a broken top elevation thereof.

Fig. 4 is a side elevation of a modified form of the invention.

Fig. 5 is a perspective view of the adaptor shown in Figs. 2 and 3.

Fig. 6 is a front elevation of the preferred form of clamping means forrigidly securing the device in operative position.

The preferred embodiment of the present invention comprises a base plateIn formed with a vertical portion H at right angles thereto, the upperend of such portion H forming a fixed jaw H! which is closed at itsforward end l3 and open at its rear end as shown at M. Thus there areformed substantially parallel, horizontal jaw portions I5 and Hi, theupper portion I 5 being provided with a downwardly extending portion I!adjacent to its rear end.

Adjacent to the lower end of vertical portion H there is provided ahorizontal aperture which receives a bolt or machine screw 20 whichpasses through a suitable aperture (not shown) at the inner end of anelongated lever 2|, such lever being of sufiicient length to provideadequate leverage during the processor extracting the tendon. Formedintegrally with the lever 2| adjacent to its inner end is a jaw 23having spaced, fixed jaw portions 24.

In most butcher shops a substantially square rail 25 is suitably mountedin spaced relation to a wall (not shown) by any suitable means, suchrail normally supporting a plurality of spaced hooks or other similardevices. The base plate i 0 is rigidly mounted on such rail 26 by meansof a substantially U-shaped support 2? which encloses the rail except onits front side, and the rear of base plate it is in contact with suchfront surface. The U-shaped support is further provided with enlargedfront terminal portions 39, and screws 3| pass through suitableapertures (not shown) in the base plate ill and thus firmly secure theplate' and its integrally formed jaw portion- !2 to the rail 26.

In use, the lower portion of the leg of the turkey or other fowl isinserted Within fixed jaw l2 and bent downwardly until the same breaksand hangs downwardly. This downwardly extending portion is then insertedbetween the fixed jaw portions 24, and lever 2| moved downwardly, thussevering the tendons from their inner terminals.

In Fig. 2 the base plate It] is shown as being rigidly secured to ahorizontal rail 34 which is generally rectangular in transverse section,rails of this relative size and dimensions being usually formed of steelrather than wood, as shown in Fig. 1. In this instance the U-shapedsupporting bracket 35 is formed with shorter horizontal portions, andbase plate I B is secured thereto by means of screws 3 I.

The adaptor 31 illustrated in detail in Fig. 5 is shown in Figs. 2 and 3in place on the fixed jaw 62 to reduce the effective width of the jawportions l5 and It. This adaptor is desirably cast in a single piece,and includes a lower U-shaped portion comprising walls 33 and 39 whichfit over the upper end of vertical portion H. Formed integrally withwall 38 is an upper offset extension t! which terminates at its rear endin a horizontal portion it? having a downwardly projecting verticalportion 43.

A horizontal opening forms spaced jaw portions 46 which are spaced aparta lesser distance than are jaw portions [5 and i6. It will thus be seenthat when the adaptor is positioned in the manner shown in Figs. 2 and 3it is rigid relative to portion H, and the jaw portions 45 may receivethe lower leg portion of a chicken or other smaller fowl.

A modified form of the invention illustrated in Fig. 4 includes a baseplate 5! having a vertical portion 52 terminating at its forward end inan upwardly extending portion 50. Extending rearwardly from said portion50 are two spaced projections 54 and 53, respectively, providing fixedjaw portions 56 and 51, respectively, the latter set of jaw portionsbeing spaced somewhat further apart than the former. On the lower edgesof the terminals of jaw projections 53 and 54 are formed downwardlyextending portions 59 and 60, respectively, which act to secure the legwithin either of the jaws during the tendon extracting operation.

It will be apparent that other changes and modifications may be made inthe foregoing device without departing from the spirit of the inventionas defined by the appended claims. In other words, the forms of theinvention described here in are illustrative only and are not to betaken in any limiting sense.

What I claim is:

1. In a sinew extractor, the combination of a base plate, a verticalplate formed integrally with and at substantially right angles to saidbase plate and an inwardly turned projection formed integrally with theupper edge of said vertical plate forming a fixed jaw which receives theleg of a fowl, a downwardly disposed extension formed at the free end ofsaid projection for preventing casual removal of the leg, an elongat edlever hinged at its inner end to the lower edge of the vertical plate,and an integrally formed fixed jaw on the lever at a point spaced fromthe inner end thereof.

2. In a sinew extractor, the combination of a baseplate, means forsecuring such plate to a horizontal rail mounted in spaced relation to awall, said means comprising a substantially U-shaped clamping elementsurrounding the rail and detachable means securing the base plate to theclamping element, a vertical plate formed integrally with and atsubstantially right angles to said base plate and an inwardly turned projection formed integrally with the upper edge of said vertical plateforming a fixed jaw which receives the leg of a fowl, a downwardlydisposed extension formed at the free end of said projection forpreventing removal of the leg during the sinew extracting operation, anelongated lever hinged at its inner end to the lower edge of thevertical plate, and an integrally formed fixed jaw on the lever at apoint spaced from the inner end thereof.

3. In a sinew extractor, the combination of a base plate, a verticalplate formed integrally with and at substantially right angles to saidbase plate and a plurality of spaced inwardly turned projections formedintegrally with the upper edge of said vertical plate forming aplurality of fixed jaws of varying widths which receive the leg of afowl, a downwardly disposed extension formed at the free end of saidprojection for preventing casual removal of the leg, an elongated leverhinged at its inner end to the lower edge of the vertical plate, and afixed jaw formed on the lever at a point spaced from the inner endthereof.

4. In a sinew extractor, the combination of a base plate, a verticalplate secured to said base plate and an inwardly turned projectionformed integrally with the upper edge of said vertical plate forming afixed jaw which receives the leg of a fowl, an adaptor comprising asubstantially U-shaped portion positioned on the upper portion of thevertical plate and including an upwardly extending jaw portion of lesserwidth than the fixed jaw and adapted to reduce the efiective width ofsaid jaw, an elongated lever hinged at its inner end to the lower edgeof the vertical plate, and an integrally formed fixed jaw on the leverat a point spaced from the inner end thereof.
